Specification of Letters Patent.

Patented Oct. 31, 1916.

Application filed December 12, 1910. Serial N 0. 596,988.

17 b all whom it may concern. Be it known that I, DUNY A. SCHUTT, a citizen of the United-States,residing at Ch1-,

cago, in the county of Cook and State of Illinois, have invented certain new and use-,

ful Improvements in Journal-Bearings, of which the following is a specification.

My invention relates to journal bearings, and in its specific embodiment is particularly adapted for the bearings of furrow opening disks as used in connection with grain drills; the object of my invention being to provide a bearing of the character indicated that will be practically dust proof, simple in its construction and eliicient in operation. I attain this object by means of mechanism, one embodimentof which is illustrated in the accompanying drawing, in wl1icl1 Figure 1 represents a side elevation of a furrow opening disk having my invention forming a part thereof Fig. 2 is a vertical sectional elevation of Fig. 1; Fig. 3 is a side elevation of the disk support; F i is a vertical section of Fig. 3; Fig. 5is an end elevation of the bearing block; Fig. 6 is a side elevation of Fig. 5; and Fig. 7 is a rear elevation of the cup-shaped casing that incloses the bearing block.

The same reference numerals designate like parts throughout the several views.

1 represents a drag bar,'to the rear end of which is secured a circular disk supporting member 2, having ribs 3 projecting beyond its outer Surface, and between which the rear end of the drag bar is received- 4t represents an angular cavlty 1n the oppo-' site side of the support that is adapted to receive an angular boss 5 at the inner end of the bearing block6, the bearing block having a bearing portion .7 upon its body and a'circular fiange-l1ke head 8 at its opposite end,

the bearing block being secured to the disk support and drag bar by means ofa through bolt 9. r

10 represents a concavo-convex'furrowopening disk that is provided with a central opening permitting the passage of the head.

of the bearingblock, and llis a cup-shaped casing inclosing thev bearing blockand having an outer flange portion12whereby it is secured to the concave surfaceoi the disk.

7 13 represents an annular grooveupon the rear side of the casing adjacent the disk support and concentric with the axis of the bearing blockand adapted to receive an anresponding shoulder 18 on the periphery of the support in a manner to span the joint between the two members, the ring being free to turn upon either member.

19 represents a circular plate secured to the convex suriace of the dlsk and contacting with the outside surface of thehead of the bearing" block near its periphery and provided with a saucenshaped depression 20 on the inner surface of its central portion.

As a further precaution against the entrance of dust and also for the purpose of supplying lubricant to the rotative parts of the bearing I provide a pressure grease cup 21, attached to the upper end of a short pipe 22 that is connected at its lower end with the disk support, and 23 represents an oil duct communicating with the pipe and with I the angular cavity in the support. The boss 5 of the bearing block. is provided withlongitudinally arranged oil slots '24 that extend into the inner surface of the bearing portion of the block in the form of grooves that communicate with radially arranged openings 25 through the block at the junction of its:bearingand head portions. The head portion of the bearing block is provided with a counterbored portion 26 that receives the head of the bolt 9, and also forms a receptacle for the lubricant, and 27 represent grooves in the headot the block that facilitate the passage of the lubricantto the hearing surfaces.

Such a hearing as I have shown and described is, for all practical purposes, absolutely dust-proof. With an oiling device for supplying lubricant to all parts of the bearing in even quantities under pressure, dust will thereby be excluded. The yielding packing material prevents the loss of oil and undue entrance of dust, while the dust-exeluding ring combines to add greater eflicacy to the dust-proof qualities of the bearing. This hearing will be found to give the best results with all parts assembled and combined in the manner shown, although I am aware that it is possible to adapt the several novel features thereof to different arrange-- ber having an annular laterally extending flange thereon, a cooperating bearing member having a cooperating coaxially disposed flange extending into proximity thereto, and a ring of greater diameter than said flanges freely rotatable with respect thereto and normally engageable only with the upper surfaces thereof.

2. In a journal bearing, a rotatable member having an annular laterally extending flange thereon, a bearing member having a cooperating flange extending into proximity thereto, packing material disposed between said flanged members and inclosed by a flange thereon, and a ring of greater diameter than said flanges freely rotatable with respect thereto and normally engageable only with the upper surfaces thereof.

8. In a journal bearing, a rotatable member having a plurality of annular laterally extending flanges thereon, a member having a flange extending into proximity to one of said. flanges, a bearing block carried by said last mentioned member and engageable with the other flange, and a ring of greater diameter than said adjacent flanges freely rotatable with respect thereto and normally engageable only with the upper surfaces thereof.

4. In a journal bearing, a rotatable member having a plurality of annular laterally extending flanges thereon, a member having a flange cooperating with one of said flanges and extending into proximity thereto, a bearing block carried on said last mentioned member and engageable with the other of said flanges, packing material disposed'between said first mentioned flanges, and a ring of greater diameter than said cooperating flanges freely rotatable with respect thereto.

5. In a journal bearing a rotatable member, a supporting member, one of the same having an annular tongue thereon and the other having an annular groove receiving said tongue, packing material in said groove and disposed around said tongue, .a bearing block on which said rotatable member is rotatably mounted detachably secured to said supporting member, and a freely rotatable dust-excluding ring disposed exteriorly of said annular groove and engageable only with the upper surfaces of said rotatable and supporting members.

6. In a journal bearing, a rotatable member, a supporting member therefor having a laterally disposed angular recess therein,

a bearing block having a plurality of angular spaced lateral extensions thereon receivable in said recess and a reduced boss portion intermediate its ends and an enlarged flanged portion at its opposite end, a ro tatable member inclosing said flanged portion having a flange engaging with said boss portion, a bolt extending through said bearing block and clamping the same to said supporting member, and means for supplying lubricant to said angular recess in said supporting member.

7.
